Revit/AutoCAD Automation Add-In Development

@augurstech

A Warm Hello! We are readily available to start working on this project! We are having hands-on experience building production-grade Revit and AutoCAD add-ins using C#/.NET. Our team has delivered multiple BIM/CAD automation tools used in real-world architectural and engineering workflows, including geometry extraction, rule-based model validation, and intelligent element placement. You are looking to develop a custom add-in that will: - Perform geometric analysis of rooms, walls, and related elements - Accurately identify and classify BIM elements within Revit/AutoCAD models - Apply rule-based automation logic for model analysis and intelligent element placement - Be built as a robust, maintainable plugin, not a prototype-only solution - Allow for future enhancement, including AI / data-driven logic I am available online for the interview else we could fix a meeting and discuss the project in detail. I am Sincerely looking forward to communicate with you as a person and I would really appreciate if you give us your valuable time. Regards, Ana

Over the last couple of years, I have worked with construction companies in North America, primarily specialized in precast concrete, to bridge the gap between BIM and ERP systems using C#/.NET. Revit Automation: I developed a solution with dual logic paths to create or update Manufacturing Orders. It handles change management by comparing model data against database records, automatically reconciling material lines for unstarted orders if discrepancies are found. AutoCAD Automation: I built tools to extract BOM data directly from custom blocks. To ensure robustness, I implemented manual fallback modes for missing geometry and strict safety checks to prevent overwriting released orders. Although my recent work focused on data integration, I am already comfortable navigating the Revit and AutoCAD APIs. I can easily adapt that experience to handle the geometric analysis and rule-based placement you need for this project. I cannot publish screen recording and code snippet as project is done for company, and it is confidential. I can show you some parts if you contact me for further conversation. Contact me to talk about details. Regards Vladimir

Hi there, I can build a clean C#/.NET add-in for Revit and AutoCAD that extracts geometry, identifies rooms and elements, and applies your rule-based automation logic right inside the BIM workflow. I’ll start with a focused POC inside your existing architecture, then extend it into a full production plugin with stable API interactions and optional AI/computer-vision enhancements. Everything will be delivered in clear stages with real API-level code, solid documentation, and examples that match how your team works. 1. Which version(s) of Revit and AutoCAD should the add-in officially support? 2. Do you already have a preferred ruleset or should I help define the logic and data structures for the automation engine?

Hi, I’m a C#/.NET developer with production-level experience building automation add-ins for both Revit and AutoCAD, including geometry extraction, rule-based analysis and automatic element placement. I can deliver a staged solution starting with a POC that identifies rooms/elements, parses wall and boundary geometry, and applies your initial rule set. From there I’ll extend into a full automation engine integrated cleanly into your existing architecture. I’ve also worked on BIM workflows enhanced by AI and computer-vision routines (layout validation, anomaly detection), so adding intelligent analysis later will be straightforward. I can provide a short screen recording of a similar plugin and a real API usage sample as requested. Best regards, Joseph

I build production-grade C#/.NET plugins for Revit and AutoCAD with a focus on geometry extraction, rule-based checks, and automated element placement, so your requirements are right in my lane. I can extract room/wall geometry, classify BIM elements, and run a rule engine that flags issues and auto-places content based on your logic, all wired cleanly into your existing architecture and delivered in stages (POC → extended product). I’ve previously integrated AI/data processing into CAD/BIM workflows (e.g. layout validation, pattern detection), so adding ML or computer-vision elements later will be straightforward. I can share a short screen recording of a similar plugin in action plus a concise code sample using the Revit/AutoCAD APIs once we’re in chat. Best regards, Waqas Ahmed

@Julian29

Hello, I’m a senior C#/.NET developer with 11+ years of experience building automation tools and custom add-ins for Revit and AutoCAD. I’ve delivered production-level BIM extensions involving geometric extraction, rule-based validation, automated element placement, and data-driven model analysis. Your requirements align closely with previous work where I built tools for room detection, wall geometry parsing, clash checks, and automated annotation/placement logic. For your add-in, I will structure a clean, modular architecture: • Geometry engine to extract rooms, walls, and element boundaries • BIM inspector to classify elements and run rule-based logic • Automation module to place components and flag exceptions • Logging + diagnostic utilities for debugging and QA I can deliver an initial POC quickly (basic geometry extraction + room identification), then extend into full workflow automation. If required, I can also integrate AI/CV pipelines—e.g., detecting patterns, validating layouts, or processing model snapshots. Deliverables include the add-in (Revit/AutoCAD), documented C# source code, API references, build instructions, and a short video walkthrough. I can also provide a recorded demo and real API code examples from my past work as requested. Happy to discuss scope and milestones. Ready to start immediately. Thanks.
